ADOLF MANDEL, OF NEW YORK, N. Y.

BUTTON.

SPECIFICATION forming part of Letters Patent No. 447,782, dated March 10, 1891.

Application filed November 26, 1890. Serial No. 372,731. (No model.)

To all whom it may concern Be it known that I, ADOLF lVIANDEL, a citizen of the United States, and a resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Buttons and Studs, of which the following is a specification.

My invention has reference to improvements in sleeve and collar buttons and studs of that class in which hinged shoes or arms are employed for securing the button or stud in its applied position.

It has for its object to provide a button of this class which can be cheaply produced and readily applied and fastened.

To this end my invention consists, essentially, in a button containing two hinged spring-arms constructed to fold one within the other into the same plane for the introduction of the button and to swing in opposite directions through an angle of approximately ninety degrees each for retaining the button after insertion, all of which is more fully pointed out in the following specification and claim, and illustrated in the accompanying drawings, in which Figure 1 represents a sectional side elevation of a sleeve-button embodying my invention. Fig. 2 is an end view of the same. Fig. 3 is a view similar to Fig. 2, but showing the arms spread open. Fig. 4 is an end View of the front plate and shank, the arms being detached. Fig. 5 is a section in the plane at as, Fig. 1. Figs. 6 and 7 are face views, respectively, of the two arms detached.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the front plate, which may be made in any desired shape and of any suitable material.

13 is the shank, which is bifurcated or yokeshaped, and is attached to or formed integral with the front plate.

0 and D are the two arms for securing the button in position, said arms being U-shaped and made of brass or any other material possessing the requisite strength and elasticity for the purpose. The arms 0 and D are constructed to fall one within the other in the same plane with the shank to form a continuation of the latter when the button is to be inserted. The arm 0 is here shown as made smaller in dimensions than the arm D. To hinge the arms to the shank, the arm D is provided with two inwardly-projecting pins a a, adapted to enter opposite holesb b,f0rmed in the two prongs c o of the said shank, and the arm 0 is provided with two outwardlyprojecting pins cl cl, adapted to enter the same holes as the pins a a, but from opposite sides. Anyother suitable hinge, however, could be substituted for the onehere described. To look the arms when unfolded or in their transverse position,as seen in Fig. 3, they are in the first place sprung upon the shank, so that their upper ends bear tightly against the prongs d d of the shank, and the latter is provided with transverse notches, as e e and f f, into which said ends snap when in their said unfolded or transverse positions. Similar longitudinal notches, as g g and h h, may be provided to look the arms when folded, Fig. 1. In both instances the notches and the ends of the arms may be slightly beveled. To insert the button, the arms are brought into the position shownin Fig. l to permit the said arms to be passed through the buttonholes, whereupon the arms are snapped into their transverse positions to lock the button.

IV hat I claim as new, and desire to secure by Letters Patent, isr In a button, a yoke-shaped shank, spring arms adapted to fit one within the other and hinged to the shank to fall into a common plane when folded to form a continuation of the shank, in combination with the notches e e,ff, g g, and h h on opposite sides of the shank engaged by said arms to hold them in their ultimate positions, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 22d day of November, 1890.

ADOLF MANDEL.
